I have come across an FN browning Model 10/22 ,380 automatic pistol with unusual markings. On the right side of the slide it says Bojho and a second word which looks like cyrillic characters and an issue number 12,xxx. It appears that tese markings were appled at the factory. A lanyard loop is found on the left side of the crip. I would guess that it was used by a military or national police force in some balkan nation. Has anyone ever heard of an FN Browning marked like this?
